Description
The PS301/PS302/PS303 are improved high precision, medium
voltage analog switches designed to operate with single power
supplies. The PS301 is a single-pole single-throw (SPST), nor-
mally open (NO) switch. The PS302 has the same pinout as the
PS301 but is a normally closed (NC) switch. The PS303 has one
normally open (NO) and one normally closed (NC) switch per
package. Each switch conducts current equally well in either
direction when on. In the off state each switch blocks voltages up
to the power-supply rail.
With a +5V power supply, the PS301/PS302/PS303 guarantee
<60
ON-resistance
.
ON-resistance matching between channels
is within 2
. ON-resistance flatness is less than
6
over the
specified range. All three devices guarantee low leakage currents
(<100pA @ 25oC, <10nA @ +85oC) and fast switching speeds
(tON < 150ns). Break-before-make switching action protects
against momentary crosstalk (PS303).
For single-supply operation below 5V, the PI5A317/318/319
are also recommended.
